6.27 Informative examplesThe alternating mode call handling (voice and fax, or voice and data) and the data call setup commands are defined suchthat the dialling command of V.250 [14] ( D) still always originates a call. The purpose is to support all current TEapplications using the dialling command as default. Fax calls are controlled following the rules of ITU-T T.31 [11] andT.32 [12] standards.

An example where a voice call is originated:

ATD+1 812 555673I; (type of address defaults to 145, CLI presentation is restricted for this call)OK (call setup was successful)

An example where a voice call is attempted from a phonebook:ATD>"Doe Joe"G; (enable CUG control for this call)+CME ERROR: 22 (entry "Doe Joe" is not found)

3GPP

3GPP TS 27.007 V8.3.0 (2008-03)44Release 8


45/185

Also supplementary services may be controlled using dial command according to 3GPP TS 22.030 [19]. An example of call forwarding on no reply for telephony with the adjustment of the no reply condition timer on 25 seconds:

ATD**61*+1812555673*11*25#OK (modification was successful)

Two new commands are created for controlling the alternating mode calls. First one, Call Mode ( +CMOD), selects between single and alternating mode. Because this is a crucial command, it is defined that the value is set back tozero (single mode) after every successfully originated alternating mode call. Also on power-up and factory or user resets, the value is set to zero. The second new command, Hangup Call ( +CHUP), is not a replacement of V.250 [14]command H, but a command which reliably disconnects the call in GSM/UMTS network. This is defined because the Hcommand is used to switch from fax or data mode to voice mode.

The setting of GSM/UMTS bearer service (data circuit duplex asynchronous and synchronous, PAD access circuitasynchronous, or data packet duplex synchronous), is done with Select Bearer Service Type ( +CBST). It chooses one of the four mentioned bearer services, the data rate of the service (or actually the modulation when modem IWFs areused), and enables or disables RLP. Command Radio Link Protocol ( +CRLP) is used to set the RLP parameters in theradio path.

Service Reporting Control command ( +CR) is defined similarly as the reporting of modulation, V.18, error control, anddata compression which are V.250 [14] features used to show information about the type of the established connection

before the CONNECTintermediate result code. +CR command has one subparameter which specifies whether theintermediate result code +CR: is returned or not. The result code should be returned before any V.250 [14]reporting result codes. An example of setting up an asynchronous 9600 bit/s modem connection with service reporting:

AT+CBST=7,0,1 (asynchronous modem 9600 bit/s and RLP)OKAT+CR=1 (enable reporting)OKATD1234567890+CR: REL ASYNCCONNECT 9600

As GSM/UMTS network offers more information about the reason of the failure in call originating and answering than

normal PSTN, it is useful to add an extra command to return this information to the TE. This information should not bereturned always after unsuccessful call originating or answering, because many TE applications look for just the regular NO CARRIER , BUSY, NO ANSWERand CONNECTmessages. Action command Extended Error Report ( +CEER) doesnot have any subparameters, and it returns the cause of the latest call setup failure. This information may be the textual

presentation of the GSM/UMTS network failure code (refer TS 24.008 [8] Annex H), or some other informationdefined by the TA manufacturer.

7 Network service related commandsThis clause describes GSM/UMTS network related commands, which are not covered in call control clause of the

present document. Commands include GSM/UMTS supplementary service handling, MSISDN query, MT and network facility locking, and network registration information query.

Description

Set command forces an attempt to select and register the GSM/UMTS network operator. is used to selectwhether the selection is done automatically by the MT or is forced by this command to operator (it shall begiven in format ) to a certain access technology, indicated in . If the selected operator is notavailable, no other operator shall be selected (except =4). If the selected access technology is not available,then the same operator shall be selected in other access technology. The selected operator name format shall apply tofurther read commands ( +COPS? ) also. =2 forces an attempt to deregister from the network. The selectedmode affects to all further network registration (e.g. after =2, MT shall be unregistered until =0 or 1 isselected). Refer subclause 9.2 for possible values. This command should be abortable whenregistration/deregistration attempt is made.

Read command returns the current mode, the currently selected operator and the current Access Technology. If nooperator is selected, , and < AcT> are omitted.

Test command returns a set of five parameters, each representing an operator present in the network. A set consists of an integer indicating the availability of the operator , long and short alphanumeric format of the name of theoperator, numeric format representation of the operator and access technology. Any of the formats may be unavailableand should then be an empty field. The list of operators shall be in order: home network, networks referenced in SIM or active application in the UICC (GSM or USIM) in the following order: HPLMN selector, User controlled PLMNselector, Operator controlled PLMN selector and PLMN selector (in the SIM or GSM application), and other networks.

It is recommended (although optional) that after the operator list TA returns lists of supported s and s. These lists shall be delimited from the operator list by two commas.

The access technology selected parameters, , should only be used in terminals capable to register to more thanone access technology.

Description

This refers to Advice of Charge supplementary service (3GPP TS 22.024 [26] and 3GPP TS 22.086 [27]) that enablessubscriber to get information about the cost of calls. With =0 , the execute command returns the current callmeter value from the MT.

The command also includes the possibility to enable an unsolicited event reporting of the CCM information. Theunsolicited result code +CCCM: is sent when the CCM value changes, but not more that every 10 seconds.Deactivation of the unsolicited event reporting is made with the same command.

Refer subclause 9.2 for possible values.

NOTE: Advice of Charge values stored in the SIM card or in the active application in the UICC (GSM or USIM)(ACM, ACMmax, PUCT) can be accessed with generic or restricted SIM access command ( +CSIM or +CRSM)).Those values can be more readily accessed with commands +CACM, +CAMMand + CPUC.

The Read command indicates whether the unsolicited reporting is activated or not. Read command is available when theunsolicited result code is supported.

It is recommended (although optional) that the test command returns the supported mode values.

Defined values
